Section 18. Timer Interface Module (TIM)
18.1 Introduction
This section describes the timer interface (TIM) module. The TIM is a two-channel
timer that provides a timing reference with input capture, output compare, and
pulse-width-modulation functions. Figure 18-1 is a block diagram of the TIM.
This particular MCU has two timer interface modules which are denoted as TIM1
and TIM2.
